Yesterday I click on a video called 'learning phyton for Beginners'. Today youtube's algorithm sent this video. I was so confuse but somehow listen to it and when I feel I understand something from this explanation, it makes me excited. A genius can make someone understand complicated things, I am very grateful.
For anyone getting an error related to converting a list to a float, the model.evaluate is actually returning a list. She has the correction in the code at around 2:05:51, but she doesn't explicitly mention the correction. You just grab the first value in the list (which is why she puts [0]). So change the line where you obtain the val_loss to: val_loss = model.evaluate(X_valid, y_valid)[0]
Happy to help, everyone. It caught me a little off guard at first, and by the way she was using it I knew it had to be a collection of some sort and it turned out it was some little change she made and forgot to mention. No biggie, but it can definitely cause a headache - I know :-)
I've been trying to learn ML for quite awhile but could never really grasp the algorithim. She explains how the formula comes about and why is it used in the classification or regression so well. My god. Thumbs up for sensei Kylie and free code camp!!!
Yeah same I'm always interested in learning where the algorithms and concepts we use in machine learning comes from and she explained it the most clearly to me. Thank you!
I have to agree with those calling this tutorial too hard. I am a professional developer studying Cyber-Sec at the Master's level and found the first hour of the tutorial to be so intimidating that I had to go and learn Python again, just to boost my confidence. I followed it by getting a tutorial on Pandas as well as Numpy, those helped. I came back and realized that, while this is a really good tutorial, it isn't beginner-friendly at all. The kind of stuff Kylie accomplishes in a single line needs multiple lines from me and many more minutes to understand what's going on. As advice to all the newbies, don't be intimidated, try taking the Python basics, Pandas and Numpy courses before attempting this tutorial, perhaps watch the first hour to see what's required and come back.
@@devafterdark don't go hard on him! I personally have 0 experience of numpy or pandas but the logic she explains is very simple, remember you're here to learn ML concepts, you can revise python syntax later.
day 1 (8/8) -> 58:35 day 2 (9/8) -> 2:34:27 day 3 (18/8) -> The end Thanks for this great course! I think that this course is not for absolute beginners despite the description, maybe if you've used libraries like Numpy and Pandas, but not for "absolute beginners". Nevertheless, she is an amazing tutor and this course is amazing for an overview. I suggest searching for a great visual of classification of ML and watch the course later on.
i think the main concept and ideas behind this can be grasped by complete begginers too, maybe the coding part would go over the head but atleast they understand the core concepts
I fell asleep once and ends up on this channel with a video about how to make a neural network playing. There was also a time when I fell asleep watching a video about nihilism on repeat and a character in my dream said what the video was saying word for word. It freaked me out.
I once fell asleep watching a space and time tv shows , in the dream I could understand what the guy was explaining in the docu , it’s crazy how the real speech of a person is translated in a dream .

The way she explained bayes theorem I generally donot find such clear explaination anywhere It was reallized and practical explaination . Truly appreciative
I just finished watching the entire video, taking a few days off to rest. Meanwhile, I also typed out all the code on Colab, mimicking what was shown. Overall, this video gave me a preliminary understanding of machine learning and opened the door to this unknown field for me. Of course, there is still a lot I need to learn, and many concepts are not very clear to me yet. However, with the prevalence of ChatGPT now, I can ask questions whenever I don't understand something. Compared to the previous technical environment, ChatGPT has made my learning process faster and more efficient. Finally, I would like to thank the blogger again. Perhaps, in the not-too-distant future, I might also make videos to guide others in getting started, haha.
Kudos, bro. I am doing the same, whenever and whatever I don't understand something, I will just head over to chatGPT and ask him to explain what is going on. I haven't watched it fully, but I benefited a lot even from the beginning.
Kylie is such a great teacher and obviously not only understands but applies these topics in the real world. What a great combination, thanks for the course!
@@leagueofotters2774 Because it's obvious to anyone interested in machine learning that Python is the language you use. If you can't even recognise that the language she used in the video is Python, what are you doing watching a course on machine learning?
I recently completed the ML tutorial, and I wanted to express my gratitude for the outstanding content. The derivation and mathematical explanations were particularly impressive. I've been trying to grasp the fundamentals of machine learning for quite some time now, and this is the first tutorial where I genuinely understood the derivations and gained valuable knowledge about the topics plus the side by side implementation also helped alot. Thank you for creating such an informative and well-structured tutorial!
I think it is a very advanced video honestly. it should mention that you need a very solid foundation of statistics, coding, data science to even understand what is going on!!! its a medium level video
If only everyone recognised the value of courses like this as you have done. First time I've seen that thanks/donation button which is sad but now will know how to contribute back! Thanks for letting me know that exists :D
Levei exatos 3 meses e 6 dias pra terminar esse vídeo assistindo em 10 momentos (parcelados) diferentes e hoje eu concluí ele Estou muito contente por ter finalizado esse compromisso e por ter consumido todo esse conteúdo Excelente material, muito didático e insightfull (não sei qual melhor expressão pra isso em pt-BR) esse conteúdo, excelente
Yes, as everyone is the audience let's start with an example that few can relate to and then just jump into code, again, everyone is well versed in code, without any explanation or overview.
What do you mean, she started off with code, but quickly went on to explain what was going on. Besides, if you want to learn ML, you should be familiar with basic python and linear algebra.
If you're getting an error about comparing a list to a float. Changing the "least_val_loss" variable to a list with two infinite floats will fix it. Like this: least_val_loss = [float('inf'), float('inf')]
@@sigmaohiofortniterizz That section had the correction edited out. Right after she says "now we wait" (2:05:50) the video skips her debugging and cuts straight to the correct code. Notice the [0] that gets added to the "val_loss = model.evaluate(X_valid, Y_valid)" line right after the "now we wait".
when compling the model we asked for metrics, binary_crossentropy and accuracy, nn_model.compile(optimizer=tf.keras.optimizers.Adam(lr), loss='binary_crossentropy', metrics=['accuracy']), so val_loss = model.evaluate(X_valid, y_valid) returns a list with those two datapoints val_loss[loss, accuracy] we are only interested in loss to plot so val_loss[0] is needed.
This is amazing. I'm a data analyst and had some formal training in machine learning, but my classes were really surface and "teach yourself" style. This is so much better. I also find it easier to listen to women, so that's a bonus lol
Spent 5 days on this video and it really taught me a lot about ML, it might be tougher for absolute beginners to grasps at first due to the knowledge of numpy and maths needed. But Beginner friendly or not, this was a good tutorial
It would be very beneficial for beginners to make Shallow, Deep and Convolutional Neural Networks from scratch. Because by doing so, they can learn many activations and their derivatives, forward propagation, and backward propagation. Along with, the dimensions of matrices and what is actually happening at each layer. Later on, they can shift to Tensorflow or Scikit when doing professional learning but I do advise to at least implement a neural network from scratch.
@@lakshman587 Yes. A Shallow Neural Network. This week I will be making a Deep Neural Network Vectorized Approach from scratch and 2 weeks later I will also implement CNN from scratch
@@muhammaddarab7474 Can you share your code? I have tried to hardcode the backpropagation algorithm for 1 input and 1 output with only 1 hidden layer So even I need to implement full NN from scratch...
@@lakshman587 I can share my Shallow Neural Network code with you for 1 layer but for N Hidden layer (Deep Neural Network), you will have to wait till I implement it
@@muhammaddarab7474 Ok I guess we are on same track. Ill try to implement NN for N hidden layers from scratch... Let's hope we will finish and gain knowledge on how NN works 🥲 All the best!
She is so good at this I woke up yesterday and startng writing an entirely custom Vector Matrix AI learning algorithm from scratch . After watching her explain the concepts from the simplest to the more complex. As a software programmer this has been very interesting to see how simple these algorithms really are.That is how you know you're a good teacher when im not even paying attention and somehow it sticks😁
It was a good watch, I think I still have a long way to go But I was able to understand the course and got lots of doubts as well. Very good course for some one who know basic concepts wanting to improve them. I would recommend this to someone who has an idea of what machine learning, because it is not entirely beginner friendly. Learn the basic concepts and come watch this to understand better about it
I cannot even begin to describe how useful this video was for me. Endless thanks for the priceless knowledge Kylie and freeCodeCamp provided. This video seriously gave me an edge when it came to machine learning. It organized all the abstract concepts I have been hearing about while also describing them perfectly. I have learned SO much. Thank you, thank you, thank you!
Had to learn ML and had no idea where to start, how to start, though I had heard of certain terms and knew bits and pieces (and was confused). This has given me a good overview of the basics and the basic concepts and contents of ML are sort of organized in my mind now with the "what is ML?", "what are the basic methods" and most importantly, "why the methods" and "How they work" information clearly explained and examples of how to use the methods on python, so that it is now easy to take off from here - A relatively comprehensive yet brief overview - a need of the hour for me right now as I cannot afford to spend weeks or months learning everything, but needed a good overview for my tasks at hand. Searched many sources but this seems to be one of the best in clarity. Thank you!
Such a great video. I’m already 30min and learning a lot. My major is centered around AI and machine learning so I wanted a sneak peek at what’s to come. Thank you!
It's 2:16 am and I just woke up to this on my screen and yes I wanted it so badly. So strange but it's now downloaded and will watch and learn when I wake up. Thank you
I just finished taking this course. I took a while. but she explains the theory and examples. I loved the math part of it. she goes on explaining the Supervised vs Unsupervised ML tools and methods. I learnt a lot also with Pyrhon. Thanks for your effort.
Thanks for the explanations! it is really detailed, her tone is comfortable, I can easily to understand what she said and she elaborates each steps (it is so important as every self learner can know the rationale behind each steps). Hope I can watch another lesson videos of this editor!
Hey, invite you to use my AI learning tool -- Coursnap for this course! It has course outlines and course shorts, so you can get the gist of 1-hour in just 5 minutes. Try it out and boost your learning efficiency!
18:10 As soon as you mentioned "Hot Dog or Not Hot Dog", it instantly reminded me of Jian Yang's classification model from the HBO comedy series Silicon Valley. 😂 But this course is very useful and easy to grasp for beginners like us. 👍👍
Hats off.. cannot imagine that it is possible to explain these concepts in such a simple way. Thank you and please keep on posting such learning videos.
Hello, I really enjoyed the entire journey with you. This is where my journey in Machine Learning begins. I have gained enough confidence to take it to the next level. ❤❤❤❤❤❤
I was so excited to see this course because usually freecodecamp courses are for beginners but this one is not. You need to have good knowledge of numpy and other libraries to be able to learn more from this course. Really disappointing. They should let users know the basics that are required for this course. But ultimately this is a very good course and it's free so really appreciate it guys. Thanks
I think most people understand intuitively that something as complex sounding as “machine learning” will require prior knowledge. Lol. It’s like walking into an “Intro to Quantum Physics and Relativity” class and expecting to get by without understanding Newtonian physics or calculus.
I would never complain about free education - do one of their Python/numpy courses and return here. Better to build on what you know already than every course starting from 0 :)
Amazing course, I coded it along in VSCode. This made me learn quite a lot about conda, environments, etc. With this kind of hands on learning, not only I believe I can start doing data analysis and creating my own models and understanding their predictions. Thank you all so much! 👏Great work! (And well, it's not for Python noobies... Anyone past the basics with most of the libraries used can understand it)
to anyone who is starting i will suggest you should read this book -(Fundamentals of data science by Jugal K. Kalita,Swarup Roy,Dhruba K.)up to machine learning unit..and if any doubt do gpt,,it will definitely help yu to understand this wonderful course more effetively.
The best introductory machine learning video! I have tremendous respect for Kylie. I think it is the clearest and easiest to understand explanation in the world. Thank you so much.

It would be helpful for people without coding experience to explain the libraries being used, the languages, and how it works. Or to explain the bare minimums required. This seems more like it's geared to people with python programming experience as a base
@Freecodecamp you're always teaching us great skills with great mentors. Salute sir 🤗. Kindly upload the electric vehicle course if you have a great mentor available.
Wow! I started learning this morning from your roadmap and the algorithm provided me this video. And this is the best one indeed. Thank you, Kylie Ying mam. Stoked to the neuron.
Thanks for the content. This isn't for everyone though.. She speeds through so much and beginners are just sitting here going "What the hell is going on...". Looks like that was being pointed out early in the comments and then there seems to be a flood "this is so clear and fully fleshed out!" comments that have been pushed to the top.. That's a bit sus.
Could you explain what the things are that you are labeling and importing as you are doing them? It helps me to make connections in my brain if I can associate what you are doing with the reason behind it. Otherwise it is just an exercise in memorizing and just replicating what you are doing without any understanding. Thank you for sharing and all the effort put into it.
It seems that nowadays the TensorFlow Model.evaluate returns both the loss and the accuracy in a list so at around 2:05 of the video the comparison val_loss < least_val_loss is no longer working. Maybe they changed what the method returns since this video was published. I got this fixed by referring to the first element of the List (according to the docs the first item is loss and second accuracy) like this: if val_loss[0] < least_val_loss: least_val_loss = val_loss[0]
In 2:40:12 u rerun the cell with the "df['functional'] == (df['funtional'] == 'Yes').astype(int)" statement. Because after the first run of this cell there is no 'Yes' in the column all values has to be 0. So u should reconsider u'r statement at 2:42:14 " 'functional' doesn't give us any utility" .
This is a great course and thank you so much. I was able to understand and learn so many new things! Some topics I had struggled a bit were quite clear through this course.
Did a refresher on ML as it's been a while... Kylie rocks! Delivered with the right amount of theory combined with examples and importantly, clarity! Top marks!!!!!
I’ve programmed in Python for a while now but I understand nothing 😂. I think she lost me when she started doing all of the Data Science stuff and there are multiple vocabulary words that could have been explained more. Overall, no shade to her but I’m probably just a noob
Can someone confirm if this goes beyond the basics and actually helps you to build stuff? I’ve done plenty of these courses and most of them only contain basic information about a 100 different things and very little demonstration of actually building a significant project from raw data. So, my fundamentals should be fine after a bit of a brush-up but I need a course that goes beyond.
English is not my native language and I am new at machine learning but it was easy for me to understand you. i watched too many videos about ML but this is the best
hi im sorry i have a really stupid doubt related to the bayes theorem question... Please correct my logic: i thought that P(having disease) = P(True positive) + P(false negative). But acc to that, the ans to that question should be 0.1-0.01=0.09. which it isn't... Is this eqn wrong or can we not add probabilities like that or... Maybe im doing it all completely wrong. Pls help. Thank u so much
Thank you so much for your brilliant tutorials and courses Kylie (please do more!!!)! Could you please recommend some books on the mathematics of machine learning (and books that you found useful when you dived into the subject).
Yesterday I click on a video called 'learning phyton for Beginners'. Today youtube's algorithm sent this video. I was so confuse but somehow listen to it and when I feel I understand something from this explanation, it makes me excited.

For anyone getting an error related to converting a list to a float, the model.evaluate is actually returning a list. She has the correction in the code at around 2:05:51, but she doesn't explicitly mention the correction. You just grab the first value in the list (which is why she puts [0]). So change the line where you obtain the val_loss to:
val_loss = model.evaluate(X_valid, y_valid)[0]

Thank you so much! You are truly a life saver.

I came back and realized that, while this is a really good tutorial, it isn't beginner-friendly at all. The kind of stuff Kylie accomplishes in a single line needs multiple lines from me and many more minutes to understand what's going on.
As advice to all the newbies, don't be intimidated, try taking the Python basics, Pandas and Numpy courses before attempting this tutorial, perhaps watch the first hour to see what's required and come back.
Wao, thanks a lot. I will learn python until pro!
skill issue
@@devafterdark don't go hard on him! I personally have 0 experience of numpy or pandas but the logic she explains is very simple, remember you're here to learn ML concepts, you can revise python syntax later.

Thanks for this great course! I think that this course is not for absolute beginners despite the description, maybe if you've used libraries like Numpy and Pandas, but not for "absolute beginners". Nevertheless, she is an amazing tutor and this course is amazing for an overview. I suggest searching for a great visual of classification of ML and watch the course later on.
i think the main concept and ideas behind this can be grasped by complete begginers too, maybe the coding part would go over the head but atleast they understand the core concepts
can you pls help how she copied the data set information on google collab
I have no idea how my RUclips algorithm brought me here while I was sleeping but it made for some strange dreams
I fell asleep once and ends up on this channel with a video about how to make a neural network playing.
There was also a time when I fell asleep watching a video about nihilism on repeat and a character in my dream said what the video was saying word for word. It freaked me out.
@Keys for Wealth like what? I’m not curious

It was reallized and practical explaination . Truly appreciative
I just finished watching the entire video, taking a few days off to rest. Meanwhile, I also typed out all the code on Colab, mimicking what was shown. Overall, this video gave me a preliminary understanding of machine learning and opened the door to this unknown field for me. Of course, there is still a lot I need to learn, and many concepts are not very clear to me yet. However, with the prevalence of ChatGPT now, I can ask questions whenever I don't understand something. Compared to the previous technical environment, ChatGPT has made my learning process faster and more efficient. Finally, I would like to thank the blogger again. Perhaps, in the not-too-distant future, I might also make videos to guide others in getting started, haha.
Kudos, bro. I am doing the same, whenever and whatever I don't understand something, I will just head over to chatGPT and ask him to explain what is going on. I haven't watched it fully, but I benefited a lot even from the beginning.
Kylie is such a great teacher and obviously not only understands but applies these topics in the real world. What a great combination, thanks for the course!
what programming language she used in this course?
@yehiaelhariry9356 I'm pretty sure that she used python

I've been trying to grasp the fundamentals of machine learning for quite some time now, and this is the first tutorial where I genuinely understood the derivations and gained valuable knowledge about the topics plus the side by side implementation also helped alot. Thank you for creating such an informative and well-structured tutorial!
Impressive comments. Did you encounter a problem with data links 🔗? I am, how can I navigate it please?
This is my first Course which I've completed from FCC, got a good understanding on ML now, Thank you !!
I think it is a very advanced video honestly. it should mention that you need a very solid foundation of statistics, coding, data science to even understand what is going on!!! its a medium level video
Thanks for an amazingly simplified approach to ML 👍

Levei exatos 3 meses e 6 dias pra terminar esse vídeo assistindo em 10 momentos (parcelados) diferentes e hoje eu concluí ele
Estou muito contente por ter finalizado esse compromisso e por ter consumido todo esse conteúdo
Excelente material, muito didático e insightfull (não sei qual melhor expressão pra isso em pt-BR) esse conteúdo, excelente
Yes, as everyone is the audience let's start with an example that few can relate to and then just jump into code, again, everyone is well versed in code, without any explanation or overview.
What do you mean, she started off with code, but quickly went on to explain what was going on. Besides, if you want to learn ML, you should be familiar with basic python and linear algebra.
that's a losing mindset. I'd save the video and come back to it once I understood the basics used
i mean at this point you would argue she is speaking english too or what
RUclips somehow made me watch this video while I was sleeping and caused me to exceed my data plan
If you're getting an error about comparing a list to a float. Changing the "least_val_loss" variable to a list with two infinite floats will fix it. Like this: least_val_loss = [float('inf'), float('inf')]
thank you so much, that really drove me crazy. can you explain why it fixed it, and why she didn't need to do it in the video?
@@sigmaohiofortniterizz That section had the correction edited out. Right after she says "now we wait" (2:05:50) the video skips her debugging and cuts straight to the correct code. Notice the [0] that gets added to the "val_loss = model.evaluate(X_valid, Y_valid)" line right after the "now we wait".
when compling the model we asked for metrics, binary_crossentropy and accuracy, nn_model.compile(optimizer=tf.keras.optimizers.Adam(lr), loss='binary_crossentropy', metrics=['accuracy']), so val_loss = model.evaluate(X_valid, y_valid) returns a list with those two datapoints val_loss[loss, accuracy] we are only interested in loss to plot so val_loss[0] is needed.
@@michaelwindon681 can we add only one float to the list " least_val_loss = [float('inf')]" ? Does this do the same function as above
That‘’s the error I have encountered. Thank you so much!
This is amazing. I'm a data analyst and had some formal training in machine learning, but my classes were really surface and "teach yourself" style. This is so much better. I also find it easier to listen to women, so that's a bonus lol

Spent 5 days on this video and it really taught me a lot about ML, it might be tougher for absolute beginners to grasps at first due to the knowledge of numpy and maths needed. But Beginner friendly or not, this was a good tutorial

Enjoy these thorough, clear, visual explanations. She makes what we do accessible to beginners and a perfect refresh for seasoned users.
Absolutely brilliant. As mentioned in the intro Kylie is a true genius. god bless her
No idea why I woke up to my RUclips algorithm playing this, but her voice is so soothing and I think I’m in love
It would be very beneficial for beginners to make Shallow, Deep and Convolutional Neural Networks from scratch. Because by doing so, they can learn many activations and their derivatives, forward propagation, and backward propagation. Along with, the dimensions of matrices and what is actually happening at each layer. Later on, they can shift to Tensorflow or Scikit when doing professional learning but I do advise to at least implement a neural network from scratch.
Have you Built NN from scratch?
@@lakshman587 Yes. A Shallow Neural Network. This week I will be making a Deep Neural Network Vectorized Approach from scratch and 2 weeks later I will also implement CNN from scratch
@@muhammaddarab7474 Can you share your code?

She is so good at this I woke up yesterday and startng writing an entirely custom Vector Matrix AI learning algorithm from scratch . After watching her explain the concepts from the simplest to the more complex. As a software programmer this has been very interesting to see how simple these algorithms really are.That is how you know you're a good teacher when im not even paying attention and somehow it sticks😁
This is basically Machine learning for everyone who is a Python programmer. But seems to be a nice video. Will get back to this after I finish Python
You are literally the best, I've been looking for a tutorial for three days and yours works
It was a good watch, I think I still have a long way to go
But I was able to understand the course and got lots of doubts as well. Very good course for some one who know basic concepts wanting to improve them.
I would recommend this to someone who has an idea of what machine learning, because it is not entirely beginner friendly.
Learn the basic concepts and come watch this to understand better about it
This is like the tenth time RUclips algorithm auto plays this video. Guess I gotta learn machine learning now.
A great introduction into machine learning, even for someone who may not be much familiar with Machine Learning, can learn a lot.
I cannot even begin to describe how useful this video was for me. Endless thanks for the priceless knowledge Kylie and freeCodeCamp provided. This video seriously gave me an edge when it came to machine learning. It organized all the abstract concepts I have been hearing about while also describing them perfectly. I have learned SO much. Thank you, thank you, thank you!
Had to learn ML and had no idea where to start, how to start, though I had heard of certain terms and knew bits and pieces (and was confused). This has given me a good overview of the basics and the basic concepts and contents of ML are sort of organized in my mind now with the "what is ML?", "what are the basic methods" and most importantly, "why the methods" and "How they work" information clearly explained and examples of how to use the methods on python, so that it is now easy to take off from here - A relatively comprehensive yet brief overview - a need of the hour for me right now as I cannot afford to spend weeks or months learning everything, but needed a good overview for my tasks at hand. Searched many sources but this seems to be one of the best in clarity. Thank you!
Such a great video. I’m already 30min and learning a lot. My major is centered around AI and machine learning so I wanted a sneak peek at what’s to come. Thank you!

Thanks . I am an experienced java lead . I always wanted to learn Machine learning
The best teacher I have ever seen in this subject...!
I was so excited to see this course because usually freecodecamp courses are for beginners but this one is not. You need to have good knowledge of numpy and other libraries to be able to learn more from this course. Really disappointing. They should let users know the basics that are required for this course. But ultimately this is a very good course and it's free so really appreciate it guys. Thanks
I think most people understand intuitively that something as complex sounding as “machine learning” will require prior knowledge. Lol. It’s like walking into an “Intro to Quantum Physics and Relativity” class and expecting to get by without understanding Newtonian physics or calculus.
I would never complain about free education - do one of their Python/numpy courses and return here. Better to build on what you know already than every course starting from 0 :)
Amazing course, I coded it along in VSCode. This made me learn quite a lot about conda, environments, etc. With this kind of hands on learning, not only I believe I can start doing data analysis and creating my own models and understanding their predictions. Thank you all so much! 👏Great work! (And well, it's not for Python noobies... Anyone past the basics with most of the libraries used can understand it)
It seems half of us are here after falling asleep
Ahahaha, that's right! I fell asleep in front of the computer and when I woke up, this video was playing. 🤣
U r not alone lol
lol yeah, but have you realized the time difference? This happened to no one by the time the video was uploaded, that's wired..
What model did you used to predict this?
Absolutely correct😮
Same 🤣 I reckon RUclips sent it for the ad revenue on a 4h video
to anyone who is starting i will suggest you should read this book -(Fundamentals of data science by Jugal K. Kalita,Swarup Roy,Dhruba K.)up to machine learning unit..and if any doubt do gpt,,it will definitely help yu to understand this wonderful course more effetively.

She is so smart and makes things simple to understand👍
It would be helpful for people without coding experience to explain the libraries being used, the languages, and how it works. Or to explain the bare minimums required. This seems more like it's geared to people with python programming experience as a base
Hello, Kylie! You even not suppose, as much you help me with this course. Wish , that you will happy all your life
@Freecodecamp you're always teaching us great skills with great mentors. Salute sir 🤗. Kindly upload the electric vehicle course if you have a great mentor available.
Wow! I started learning this morning from your roadmap and the algorithm provided me this video. And this is the best one indeed.
Thank you, Kylie Ying mam.
Stoked to the neuron.
Thanks for the content. This isn't for everyone though.. She speeds through so much and beginners are just sitting here going "What the hell is going on...". Looks like that was being pointed out early in the comments and then there seems to be a flood "this is so clear and fully fleshed out!" comments that have been pushed to the top.. That's a bit sus.
no u actually just have needed to know programming and some basic math. This is much better than that 9hr one by that indian kid
day 1 (8/7) -> 44:43
day 2 (9/7) -> 58:35
day 3 (10/7) -> 1:39:44
day 4 (11/7) -> 2:34:28
day 5 (12/7) -> 3:53:52 done
Congrats
I love it! I must say this is one of the most comprehensive and well structured videos I've watched lately! Big kudos to Kylie!
Kylie and this course are f**ing AWESOME!!! So clear explained!! Thank you so much for sharing!
Could you explain what the things are that you are labeling and importing as you are doing them?
It helps me to make connections in my brain if I can associate what you are doing with the reason behind it. Otherwise it is just an exercise in memorizing and just replicating what you are doing without any understanding.
Thank you for sharing and all the effort put into it.
I love it how it says "for everybody" and skipping through the video all I can see is code and equations.
if you're trying to learn machine learning. you obviously need to know code and some math
Tysm for covering sooo much so quickly and it was all clear and to the point and I cant appreciate it enoughhhhhh!!!!!
i watch a lot of ml course and I believe this is best course.I don't blame on other teacher.My learning style is familier with this course
It seems that nowadays the TensorFlow Model.evaluate returns both the loss and the accuracy in a list so at around 2:05 of the video the comparison val_loss < least_val_loss is no longer working. Maybe they changed what the method returns since this video was published. I got this fixed by referring to the first element of the List (according to the docs the first item is loss and second accuracy) like this:
if val_loss[0] < least_val_loss:
least_val_loss = val_loss[0]
In 2:40:12 u rerun the cell with the "df['functional'] == (df['funtional'] == 'Yes').astype(int)" statement. Because after the first run of this cell there is no 'Yes' in the column all values has to be 0. So u should reconsider u'r statement at 2:42:14 " 'functional' doesn't give us any utility" .
Good morning guys!
Kylie, thanks so much for your time. It was a pleasure learning from you.
didnt feel like for beginners
This is the best course ever on youtube about machine learning . She know the fundamental and know what to teach . ❤
This is a great course and thank you so much. I was able to understand and learn so many new things! Some topics I had struggled a bit were quite clear through this course.
what programming language she used in this course?
@@yehiaelhariry9356 Python.
@@yehiaelhariry9356 bruh😂😂😂🤣🤣🤣
her explanation extremely helpful for my Diabetes Machine Learning Research
Thanks for making the excellent course!
Did a refresher on ML as it's been a while... Kylie rocks! Delivered with the right amount of theory combined with examples and importantly, clarity! Top marks!!!!!
I’ve programmed in Python for a while now but I understand nothing 😂. I think she lost me when she started doing all of the Data Science stuff and there are multiple vocabulary words that could have been explained more. Overall, no shade to her but I’m probably just a noob
Prefect course for newbie. Teacher explains very good. 🎉
This is so great!! Best machine learning video I have seen by far!!
Good job on this :D
She's excellent.I wish she do deep learning tutorials
Can someone confirm if this goes beyond the basics and actually helps you to build stuff? I’ve done plenty of these courses and most of them only contain basic information about a 100 different things and very little demonstration of actually building a significant project from raw data. So, my fundamentals should be fine after a bit of a brush-up but I need a course that goes beyond.
read the title once again
It is just basic not in deep knowledge
You are in what we call tutorial hell
Try to build something on your own it will help
The best way to learn is to practice. You can find free datasets online and mess with them to practice skills.
English is not my native language and I am new at machine learning but it was easy for me to understand you. i watched too many videos about ML but this is the best
hi im sorry i have a really stupid doubt related to the bayes theorem question... Please correct my logic: i thought that P(having disease) = P(True positive) + P(false negative). But acc to that, the ans to that question should be 0.1-0.01=0.09. which it isn't... Is this eqn wrong or can we not add probabilities like that or... Maybe im doing it all completely wrong. Pls help. Thank u so much
Great work! amazing job, just suited for those who want to know how we solve deep learning problems,like tools and thought
A great introduction into machine learning, even as someone who is into the tech industry, I am not too familiar with machine learning.
THANK YOU for making her course available on this channel !!!!!!! 👍😃👍
Thank you so much for your brilliant tutorials and courses Kylie (please do more!!!)! Could you please recommend some books on the mathematics of machine learning (and books that you found useful when you dived into the subject).
I don't know why, but this helped me sooooo much to finally fall asleep 👍
Thank you a lot for this video. This is very interesting and informative. Keep posting like those amazing videos, this is awesome.
Wow, talk about a masterclass in entrepreneurial wisdom! Who knew you could launch an empire with just a few bucks and a dream? 😮
Thanks for sharing such an amazing content!!
